Rachel Reeves has introduced a new tax aimed at properties valued over £2 million to ensure that the wealthiest individuals contribute their fair share. Known as the “mansion tax,” this measure is projected to affect approximately 100,000 to 200,000 homes, adding an extra £2,500 for properties exceeding £2 million and £7,500 annually for homes valued above £5 million.
This initiative by the Chancellor is anticipated to generate around £400 million annually for the Treasury, with estimates indicating £0.4 billion in revenue for the fiscal year 2029/30. Referred to as a “high value council tax surcharge,” this policy is part of efforts to address wealth inequality in the country.
Reeves emphasized the need to tackle longstanding wealth disparities, noting the discrepancies in council tax payments between different property values. Consequently, starting in 2028, the High Value Council Tax Surcharge will be implemented in England, targeting properties falling within the F, G, and H bands, affecting less than 1% of properties.
In contrast to regular council tax, which supports local council budgets, this new surcharge will be directed to the government. The council tax system in England operates on bands determined by property valuations from April 1991, with the average Band D council tax for 2025-2026 standing at £2,280.
The Office for Budget Responsibility outlined that properties valued above £2 million by the Valuation Office in 2026 prices will face an additional annual charge starting from April 2028. The surcharge will vary based on property bands, ranging from £2,500 to £7,500 for homes valued at £2 million to over £5 million.
Initially proposed with a £1.5 million threshold affecting 300,000 households, the threshold was raised to £2 million to prevent undue burden on families considered “asset-rich, cash poor.” Experts from the Institute for Public Policy Research highlighted the potential to reduce council tax bills for the majority of households, offering funding for essential public services through property tax reforms.
Responding to the tax initiative, Sarah Nankivell from the Common Wealth think tank welcomed the mansion tax as a step toward fairer contributions from the affluent. However, she emphasized the need for more substantial actions, such as aligning capital gains and dividends tax rates with income tax, to address disparities in the taxation system.
